Optical Variability Correlated with X-ray Spectral Transition in the Black-Hole Transient ASASSN-18ey = MAXI J1820+070
Keito Niijima, Mariko Kimura, Yasuyuki Wakamatsu +49
How a black hole accretes matter and how this process is regulated are fundamental but unsolved questions in astrophysics. In transient black-hole binaries, a lot of mass stored in…
Precise transit and radial-velocity characterization of a resonant pair: a warm Jupiter TOI-216c and eccentric warm Neptune TOI-216b
Rebekah I. Dawson, Chelsea X. Huang, Rafael Brahm +53
TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS Mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit transit timing…
IM Normae: The Death Spiral of a Cataclysmic Variable?
Joseph Patterson, Jonathan Kemp, Berto Monard +18
We present a study of the orbital light curves of the recurrent nova IM Normae since its 2002 outburst. The broad "eclipses" recur with a 2.46 hour period, which increases on a tim…
The Spin-Period History of Intermediate Polars
Joseph Patterson, Enrique de Miguel, Jonathan Kemp +25
We report the detailed history of spin-period changes in five intermediate polars (DQ Herculis, AO Piscium, FO Aquarii, V1223 Sagittarii, and BG Canis Minoris) during the 30-60 yea…
Infrared spectroscopy of the recent outburst in V1047 Cen (Nova Centauri 2005)
T. R. Geballe, D. P. K. Banerjee, A. Evans +14
Fourteen years after its eruption as a classical nova (CN), V1047 Cen (Nova Cen 2005) began an unusual re-brightening in 2019 April. The amplitude of the brightening suggests that…
TOI-216b and TOI-216c: Two warm, large exoplanets in or slightly wide of the 2:1 orbital resonance
Rebekah I. Dawson, Chelsea X. Huang, Jack J. Lissauer +32
Warm, large exoplanets with 10-100 day orbital periods pose a major challenge to our understanding of how planetary systems form and evolve. Although high eccentricity tidal migrat…
